Why do some affairs end in heartbreak while others end in tragedy?
In this powerful episode of Inside the Polygraph, David Goldberg examines one of the most disturbing questions in criminal investigations: Why does infidelity sometimes lead to murder?
Drawing from decades of experience in law enforcement, criminal investigations, and more than 25 years as a board-certified polygraph examiner, David explores the psychological and behavioral patterns that can transform betrayal into deadly violence. This is not a sensationalized true crime episode—it's an educational discussion designed to help listeners recognize dangerous warning signs before it's too late.
Throughout the episode, David explains how emotions such as jealousy, fear of rejection, humiliation, financial loss, obsessive control, and narcissistic entitlement can escalate into violence when left unchecked. He also breaks down several well-known criminal cases to illustrate the behavioral patterns investigators often encounter.
Most importantly, David discusses the red flags that may indicate a relationship is becoming emotionally or physically dangerous and why seeking help early can save lives.
